Numeric (Process) Measurement Definitions
The Emonitor software and the Dynamix 2500 data collector support numeric
measurement definitions. This topic lists the unique characteristics of the
Dynamix 2500 data collector that you may need to know when setting up and
collecting numeric data.
Measurements Units Not Supported in the Dynamic 2500 Data Collector
• You can make a numeric measurement definition for any available
measurement unit by setting Data Type to ‘Numeric.’
• Numeric measurement definitions with Input type set to ‘DC Coupled’
with units not supported by the Dynamix 2500 data collector map to units
of USER (eus). The input type is part of the transducer specification that
you select for the collection specification. This results in a process (DC)
voltage measurement in the Dynamix 2500 data collector.
• For a list of support measurement units, see
.
Full Scale Values for Numeric Measurements in the Dynamix 2500 data
collector
• The full scale value in the Dynamix 2500 data collector for a numeric
measurement is defined as ten times the value of the alarm or the baseline
measurement.
• If no alarm or baseline measurement exists for the measurement in the data
collector, the Dynamix 2500 data collector assumes a full scale value of
10,000.
